Partially Blank Pages or Partially Missing Color Plane on a Lexmark C73x or X73x Series Printer

For a print quality defect of this type, it is always advisable to print the following;

• Print Quality Pages to get a detailed look at the printer's output. These pages allow each color plane to be viewed independently to determine if the issue is with one color (possibly due to a single supply item), or with all the colors (indicating a more general issue with the printer). • Menu Settings Page to check the levels of the consumable supplies (i.e., items such as toner cartridges and photoconductor units). Supplies that are at or near the end of their functional lives can cause various print quality issues independently of the operation of the printer.

Note: Detailed instructions for navigating through the printer menus are provided in the User's Guide.

Using the Menu Settings Page, check the levels of the consumable supplies. If any of the supplies are low, replace them to see if this resolves the issue. Many print quality issues are caused simply by a supply item that is at or near the end of its expected functional yield. Resend the print job to the printer. Did the issue return?

Yes: Continue to Step 3.No: If the page prints, the printer is functioning correctly.

Note: Instructions for replacing supplies can also be found in the User's Guide.

Verify that all packing material has been removed from the toner cartridges and photoconductor units that correspond to the color that is not printing.

Note: Packing material on the toner cartridge may cause print quality defects such as those illustrated in the image above.
